(2,2'-Bipyridine)(4-ethynyl-2,2'-bipyridine) dichloride CAS 1801511-86-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2,2'-Bipyridine)(4-ethynyl-2,2'-bipyridine) dichloride.

(2,2'-Bipyridine)(4-ethynyl-2,2'-bipyridine) dichloride (CAS 1801511-86-3) is a high-purity analytical reference standard with the molecular formula C32H24N6RuCl and a molecular weight of 629.11 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, (2,2'-Bipyridine)(4-ethynyl-2,2'-bipyridine) dichloride is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 629.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
